Existing wasabi food product is on the market various in style, picture horseradish face, horseradish sauce, horseradish mildy wash, horseradish health products etc., but the active ingredient in horseradish does not fully extract by these wasabi food products completely, make it can not well be used as human body is absorbed, and mouthfeel is not good, nutritive value is not high, can not be applicable to all groups.
In view of this, special proposition the present invention.
Summary of the invention
The first object of the present invention is to provide a kind of horseradish sour milk powder, described horseradish sour milk powder improves the utilization rate of horseradish conscientiously, mouthfeel uniqueness is fragrant and sweet, pure natural, combine double health effect of horseradish and Yoghourt, be more conducive to absorption of human body, the advantage such as easy to carry and all-ages, brew conveniently, filled up the blank that horseradish is applied at Yoghourt manufacture field.
The second object of the present invention is to provide a kind of preparation method of described horseradish sour milk powder, the method have method simple, be easy to operation, the gentle and can completely of operating condition keeps the advantages such as the active ingredient in each component.
In order to realize above-mentioned purpose of the present invention, spy by the following technical solutions:
Embodiments provide a kind of horseradish sour milk powder, obtain primarily of following raw material: in mass fraction, milk 60-95 part, horseradish stem juice 3-12 part, leavening 0.2-1.2 part, sweetener 2-8 part.
Yoghourt is raw material with milk, after pasteurize, add beneficial bacterium (leavening) again in milk, after fermentation, then cools filling a kind of milk product.Sour milk product is many mainly with the fruit-flavor type of the auxiliary materials such as the various fruit juice jam of coagulating type, agitating type and interpolation in the market.Yoghourt because it is nutritious, be easy to digest and assimilate, and to human body, there is certain health-care effect, be subject to the favor of increasing consumer.In recent years, China town dweller Yoghourt consumption average growth rate per annum was all more than 10%.The Yoghourt of overseas market accounts for liquid milk proportion about 40%, and China only accounts for about 15%.Although liquid milk belongs to Yoghourt common form, but it carries inconvenience, preservation condition is also comparatively harsh, compare sour milk powder and not only can keep the vigor of former leavening, nutritional labeling and local flavor, and without the need to strict refrigerated condition, be conducive to the equalization making yoghurt whole year production, the supply-demand relationship that dull and rush season of adjusting saves, transport, carry and eat also easily, Production of Yogurt technology is a a progressive step, for development tourism and sports provide extemporaneous beverage.In the food industry in future, sour milk powder is promising and productivity.
More than discuss and show, the development in China's sour milk powder market still has huge potentiality.But existing market does not have horseradish sour milk powder, and this product comes out, and be that spraying dry is formed after direct fermentation for the general production method of sour milk powder in prior art, this general production technology is not also suitable for horseradish, technique dry under high temperature can cause the nutritional labeling of horseradish to be lost to the greatest extent, and the sour milk powder mouthfeel produced not is fine.The present invention is in order to solve the various technical problems of above appearance, provide a kind of horseradish sour milk powder, by horseradish and sour milk powder are organically combined, product is made to have double effects, not only overcome the defect that conventional liquid Yoghourt is all, and mouthfeel is natural, rich in nutritive value, both there is the distinctive pungent Flavor of horseradish, there is again nutritional health function that horseradish plant has itself and storage is convenient, reconstitute restoration good, viable count is high, easy to use, also the horseradish active ingredient solved in conventional wasabi food product is difficult to the problem be absorbed by the body due to its volatile Sum decomposition, it is a rare sour milk food.
Wherein, milk can be any one or a few the combination in whole milk, lowfat milk and skim milk, preferably skimmed milk, and skim milk is that the fat of normal milk is removed a part, make fat content drop to less than 0.5%, be less than 1/7 of ordinary milk fat mass.Here skim milk refers to whole skimmed milk, and for whole milk, marginal also have lowfat milk.The generation of this milk meets the nutritional need that modern pursues " high protein, low fat ", and therefore from the health of the mankind, what preferably add in the feed is skim milk.The raw material that Yoghourt indispensability inherently prepared by milk does not need to repeat at this again, except the milk that routine uses, the present invention is also creationary in the feed with the addition of horseradish stem juice, horseradish stem is the essence substance of horseradish, because of containing the necessary abundant vitamin of human body, amino acid, polysaccharide, vitamin, multi mineral prime element and trace element, there is antibacterial, antiviral, food digesting stomach fortifying, conditioning enteron aisle, beautifying face and moistering lotion effect.
In addition, the leavening added has the characteristic improving nutritive value and digestibility, also be easier to various nutriment in horseradish and change into small-molecule substance, be easier to as absorption of human body, avoid the volatile Sum decomposition of nutritional labeling in wasabi food product in the past and the appearance of the problem that difficulty is absorbed by the body, therefore horseradish and milk combination collocation are carried out fermentation and obtain sour milk powder, belong to best combination, not only the local flavor of sour milk powder is better, also being easier to each nutritional labeling in horseradish by human body is absorbed, kill two birds with one stone, the sour milk powder obtained takes into account leisure and health food double effects.This material combination mode still belongs to the first in Yoghourt manufacture field, and the sour milk powder health-care effect obtained is all good, and this nutritional labeling each with it can more preferably absorb and is undivided by human body.
In addition, also added sweetener in the feed, sweetener also has the effect of seasoning except assisted fermentation, comprise any one or a few the combination in glucose, maltose, fructose, sucrose, lactose, xylitol, D-sorbite and white granulated sugar, preferred white granulated sugar, cost of fine quality is low, if for diabetes patient, preferably selects the xylitol of low sugar.
In order to the quality of further optimizing product, the embodiment of the present invention prepare in each raw material dosage of Yoghourt, preferably in mass fraction, milk 70-92 part, horseradish stem juice 4-9 part, leavening 0.3-1.0 part, sweetener 3-7 part, more excellent is milk 80-90 part, horseradish stem juice 5-7.5 part, leavening 0.4-0.8 part, sweetener 4-6 part, the consumption of such as milk can also be 81 parts, 82 parts, 83 parts and 86 parts etc., the consumption of horseradish stem juice can also be 5.5 parts, 6 parts, 6.5 parts and 7 parts etc., the consumption of leavening can also be 0.5 part, 0.6 part, 0.7 part, 0.9 part etc., the consumption of sweetener can also be 5 parts, 5.5 parts and 5.7 parts etc.
From relative usage, milk is relatively large as major ingredient dosage, horseradish stem juice itself belongs to highly condensed nutritious material, it is higher that it is rich in nutritive value, therefore according to practice find addition when very little local flavor and nutrient content the highest, add again not only to waste raw material nor can be absorbed by human body, such as with milk 80g, so about 5g got by horseradish stem juice, if it is too much to find to add horseradish stem juice, the color and luster of product acid milk powder, mouthfeel, smell is all not good enough, have astringent mouthfeel of turning sour, and ferment effect can be affected and then have influence on the health-care efficacy of sour milk powder.These raw materials of leavening, sweetener be according to many people to the mouthfeel of sour milk powder, brew after viscosity acceptance level and keep the destroyed better consumption considered of its nutritional labeling, certainly also can consider the problem of cost.
Although horseradish sour milk powder of the present invention each raw material used all belongs to Common materials, but also do not have a kind of with this horseradish sour milk powder produced for raw material of filling a prescription in prior art, unique formula of the present invention belongs to unique product in beverage production field, for this horseradish sour milk powder of follow-up making provides the formula and concrete consumption that can refer to, there is certain reference value, and this product has extraordinary effect, for human body benefit the more.
Add the best results of the horseradish sour milk powder that each raw material obtains according to this proportioning, drinking for a long time can aid digestion, heat-clearing toxin expelling, conditioning enteron aisle, beautifying face and moistering lotion and without any side effects to human body.Mouthfeel uniqueness is fragrant and sweet, and no impurity taste is nutritious, and Yoghourt is dark green, and homogeneous free from admixture, shelf lives is long.
The present invention, except providing a kind of formula of horseradish sour milk powder, additionally provides a kind of preparation method of horseradish sour milk powder, comprises the steps:
Added water by horseradish stem and squeeze the juice, obtain horseradish stem juice for subsequent use, wherein the mass ratio of water and described horseradish stem is 1-2:1;
Mixed by milk after boiling with sweetener, cooling also adds described horseradish stem juice, leavening mixing and stirring successively, then by fermentation, homogeneous process, after vacuum freeze drying step, to obtain final product.
The preparation method of the embodiment of the present invention, have method simple, be easy to operation, the gentle and can completely of operating condition keeps the effect of the active ingredient in each component.Wherein horseradish stem juice can by commercially available acquisition, also can be prepared voluntarily, the method of preparation is: after first being cleaned by horseradish stem, get horseradish stem to add water and squeeze the juice, the temperature of squeezing the juice preferably controls below 20 DEG C, horseradish stem juice is preserved under 1-4 DEG C of condition, if the temperature too high effective nutritional labeling can destroyed contained by horseradish stem when squeezing the juice, after having squeezed the juice, Cord blood is conducive to keeping original mouthfeel and local flavor.
Also have, the interpolation of sweetener is starting to mix with milk in the process of boiling most opportunity, because sweetener needs the mouthfeel of abundant blending milk, therefore need to boil to reach the object enriching mouthfeel, the time controling boiled is at 1-2min, as long as do not need to make sweetener and milk fully merge for a long time, then cool down, add described horseradish stem juice successively, leavening mixing and stirring just completes the operation that all raw materials add, the temperature of cooling preferably controls at 40-60 DEG C, if the too high horseradish stem juice that adds of temperature can be easy to make the decomposition of its nutritional labeling dissipate, affect its health-care efficacy.
